STU lVI P-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 314,619, dated March. 3l,` 1885.

Application filed August 13, 1884. (No model.)

.To all whom it may concern,.-

Be it known that I, `GEORGE WV. STAM- BAUG-H, a citizen of the United States, residing at Troy, in the county of Madison and State of Illinois, have invented a new and useful Improvement in Stump Extractors, of which the following is a specification, reference being had to the accompanying draw- 1ngs. My invention relates to stump-paliers; and 1t has for its object to provide a device of this character which shall be cheap and simple in its construction and durable in use.

With these ends in view the invention consists in the improved construction and combinations of parts, hereinafter fully described, and pointed out in the claim.

In the drawings, Figure l is a perspective view of a stump-`puller constructed in accordance with my invention.. Fig. 2 is a vertical section of the same. Fig. 3 is a top View of the frame with the feed nut and screw remotved, and Fig.. 4 is a detail view of the feednu In the accompanying drawings, in which like letters of reference indicateeorresponding parts in all the iigures, A represents the supporting-frame, which consists of the beams B, having uprights or standards C secured at 1ts ends, said uprights or standards C being braced by cross or tie rods D, which are connected to the beam B and said nprights or standards C. The lower ends of the nprights or standards may be connected by beams or runners E, having their ends cut off diagonally. It will be seen that by the use of these runners the supporting-frame may be moved from place to place with but little trouble,

' whereas if they were not employed it would necessitate the frame being carried. Upon the upper side of the beam B is provided a rectangular recess or opening, a, and seated in this opening is a'metal plate, E, which is flush with the upper side of the beam, and which has a recess similar in form to that of the beam B. A hole or opening is also provided in said plate, and a corresponding opening or passage in the beam, and of somewhat larger diameter, is also formed. Seated in the opening or recess in the plate E is a feed-nut, b, which has its lower side rounded off, so that when the feed-screw is moved laterally a corresponding movementwill be imparted to the nut', and as it is not rigid all possibility of its becoming broken is avoided.

G represents the feed-screw, which works in the screw-threaded opening of the feednut and extends through the enlarged passage or opening in the beam B. It will be seen that as the opening or passagein the beam B is larger than the feed screw itself, said feed-screw is allowed movement in any direction; said movement, however, is limited by the sides of the passage with which the feed-screw comes in contact. Upon the upper end of the feed-screw is keyed an operating arm or lever, c, while the lower end of the feed-screw is provided with a swivel having a chain connected therewith.

The operation is as follows: The chain is attached to the stump and the feed-screw turned by means of the operating handle or lever, the swivel remaining stationary, the feed-screw turning loosely in the same. In

turning the lever or handle there is more or less movement tothe feed-screw, and as the same is socketed there is no liability of its becoming broken.

It will be seen from the above description thata stump-puller constructed in accordance with my invention is simple in its construetion, may be manufactured and supplied at a comparatively slight cost, that its operation is positive and effective, and that it is strong and durable.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improvement in stump-extractors, the combination, with the inclined standards O O', mounted on runners, of a beam, B, having an oblong recess, a, in its upper side, and..

an enlarged opening or passage extending from the recess through the beam, a plate, E, seated flush in the recess and held therein by suitable fastening means, a square recess in said plate, a feed-nut, b, seated in the square recess and having its lower side rounded off,

a feed-se1ew, G, Working in the threaded opening of the nut and extending through the enlarged passage of the beam, a'ehan attaohed to the lower end of the screw, and an operating arm or lever, C, keyed to the upper end of the same, as and for the purpose set forth.

In testimony thatl claim the foregoing as my own I have hereto afxed my signature in presence of two witnesses.
